Import Depth Gauge With Fine Adjustment — Buy in Bulk from Supplier in China

This depth gauge with fine adjustment is a precision measuring tool featuring a mono-block base available in 100mm or 150mm lengths, designed for repeatable measurements in industrial environments. The scale is etched for clarity and the thimble mechanism allows incremental adjustments down to 0.01mm resolution, suitable for applications requiring tight tolerances. The base and stem are manufactured from either carbon steel or stainless steel, selected based on corrosion resistance needs in the operating environment.

Carbon steel versions are typically hardened and coated for wear resistance in dry workshop conditions, while stainless steel variants suit wet or chemically exposed settings. The fine adjustment screw is machined to a standard pitch of 0.5mm per full turn, consistent with DIN 863 and ISO 3611 tolerances for hand-held depth gauges. No internal spring or magnetic components are used, ensuring mechanical reliability without electronic calibration drift.

This tool is commonly purchased by mechanical workshops, automotive repair shops, and aerospace component manufacturers for verifying hole depths, step measurements, and machined part dimensions. Buyers typically order in quantities of 5 to 50 units, with standard packaging in individual foam-lined cardboard boxes. Trade terms offered include FOB Shanghai and CIF destination port, with lead time typically 15 to 20 days after order confirmation.

Lishui Nanguang Measuring & Cutting Co., Ltd. is a manufacturer based in No.86 Tianning Industry Area, Lishui, Zhejiang, China, specializing in hand-held measuring tools and cutting equipment. The supplier is verified as an imported-tier entity with harbor-level trust signals, indicating active export activity and customs clearance history. The listing does not state company size, years in operation, or client names, and no certifications such as ISO are confirmed by the supplier in the source data.

The supplier's profile indicates production capability in metal measuring instruments, but no information is provided about internal quality control processes, calibration labs, or R&D activity. Response rate and average response time are not recorded, suggesting limited buyer communication infrastructure. Buyers should treat this as a factory-direct source without verified quality management documentation unless independently confirmed.
